DOOR-HANGING GAGE.

SPECIFICATION forming part of Letters Patent No. 505,868, dated October 3, 1893.

' Application filed March 3, 1893. $erial No. 464,545. (No model.)

To all whom it may concern: 1

Be it known that I, EDWARD WRIGHT, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have in vented certain new and useful Improvements in Door-Hanging Gages; of which the following,together with the accompanying drawings, is a specification sufficiently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same.

This invention relatesto an improved construction for that class of marking gages employed for laying out or marking the position for the hinges respectively upon the door and the door-jamb preparatory to cutting the-recesses for the hinge-plates therein, and for similar purposes.

The object of my invention is to provide a gage of simple and improved construction, one that is more advantageous, efficient and convenient for use, and which can be manufactured with greater facility and economy.

To this end my invention consists in a gage of the peculiar construction shown in the drawings and hereinafter particularly described.

In the drawings, Figure 1 is a top view of a gage constructed in accordance with my invention. Fig. 2 is a side view of the same. Fig. 3 is a bottom view. Fig. 4 is a transverse section at line a: w, and Fig. 5 is a transverse section at line til-20.

Referring to parts, A denotes the body or main part; B the adjustable guiding plate; 0 the clamping screw therefor; D the adjustable depth-gage marker, and F its binder or setscrew.

In my improved gage the body A is made as shown, and consists of a metal bar or plate having a straight under surface 2, with parallel edges, as at 3 3. At one end said bar is furnished with integral flanged projections t that formthe rabbet-gaging head 5, the end face of which is at right angle to the axis of the bar. The central part of the bar adjacent to the head is raised, as at 6, and a vertical longitudinal slot. a is formed therethrough, extending from about the mid-length of the bar nearly tothe head end thereof. The top surface of the raised portion6 is parthe under surface of the bar, against which it is retained by the screw 0. The shank 8 of the screw extends through and fits within the slot at with a close running fit that permits of its being moved along the slot While its threaded end 9 screws into a threaded opening formed in the front end of the slideplate B, as shown, the collar 7 of the screw 'resting on the top surface at the sides of the slot, as indicated.

The rear end of the plate B and the guideflange B thereof are retained in proper lateral relation to the bar by the lugs 10 and the front end of the plate by the cylindrical body or shank of the screw- 0 fitting in, thereby avoiding the necessity of dovetailed guiding screws at the end of the main bar. The marker point J is fixed in the front end of the slide-plate B, and said slide-plate 15 slotted at b to accommodate the marking point E'which is fixed in the bar A. A marking point G for common gage work is best arranged in the rear end of the bar.

At its rear end the bar A is provided with an upwardly projecting integral bearing boss 'A having a longitudinal hole therethrough parallel with the bar axis. A cylindrical short rod or 'pin D, having its outer end upset or flanged to form a beveled edged head or marker d, is fitted in said bearing and retained at position of adjustment by a setscrew F fitted in the top of the boss and screw ing against the side of said marker-rod. The inner end of the marker-rod is provided with a pin orstop 12 that prevents its escape from the bearing. The end surface of the bar and bearing A is squared oif, as at 15, and serves as the guide when using the marker D. The clamp-screw 0 being arranged at the front end of the slide plate and passing through the slot in the main plate with a close running fit therein holds the point-carrying end of the slide plate firmly in place and obviates the necessity of dovetailing the edges of the slide plate into the bar, while the shoulders 10 prevent lateral displacement of the rear end of the slide-plate and the downwardly turned guiding lip B. The parts can be readily manufactured and assembled and the Whole makes a very compact and efficient structure.

When using this gage the point J serves for marking the rabbeteddoor-frame, the head 5 runs against the jamb; while pointE serves for marking the edge of the door with the plate B run against the angle thereof; the relative position of the points J and E being such that adjustment of the slide-plate B B properly sets both said gaging points; the manner of using being substantially as here tofore practiced with gages of this class. It will be understood that I do not broadly claim a door gage having two marking points so arranged that a single adjustment serves for setting the gage for both the j-amb-rabbet and the edge of the door; as such feature has been heretofore embraced in purpose named.

I clatm- 1. In a door-hanging gage the bar A having the straight bottom 2 and parallel side edges t 3, the integral flanged head 5 and raised top gages for the portion 6 provided with a vertical slot at through the center thereof, extending lougiturlinally from near the head to about midlength of the bar, the slide-plate B fitting against the bottom of said bar and provided at its rear end with the transverse downward projecting guide-flange B with upward shoulders 10 that embrace the parallel edges of said bar, the thumb-head clamp-screw, its body 8 fitting within said longitudinal slot, its end 9 screwing into a threaded openingin the front end of the slide-plate, and havinga shoulder 7 that rests upon'the raised portion of the bar, and the marking points J and E, substantially as set forth.

2. The within described gagetool having its bar formed with the longitudinal vertical slot and the transverse head at one end, and the upwardly projecting bearing boss at its opposite end, the slide-plate matching the under side of said bar, the bevel headed marker-rod adj ustably supported in said bearing boss, the marking points respectively fixed in said bar and slide-plate, and the binder-screws for retaining said marker-rod and slide-plate, all arranged substantially as shown and described.

Witness my hand this 28th day of February, A. D. 1893.
